研磨是一种精密的加工方法,在精密仪器和精密机械的装配中广泛应用。圆柱小孔的研磨在精密仪器的装配中经常会遇到。由于圆柱小孔的直径小,研磨具的设计要受到尺寸限制,要求研磨具的结构不能太复杂,因此,圆柱小孔研磨具的设计与一般圆柱孔研磨具的设计相比,有其本身的特点。本文论述直径为φ1～φ4的小孔研磨具的设计。对这类研磨具的要求为:①直径比工件直径小0.01～0.025mm;②工作部分长度一般比工件长1/2左右。设计研磨具时,首先应按孔径大小、工
Grinding is a precision machining method that is widely used in the assembly of precision instruments and precision machinery. The grinding of cylindrical holes is often encountered in the assembly of precision instruments. Due to the small diameter of the small cylindrical hole, the design of the abrasive to be subject to size constraints, the requirements of the structure of the abrasive can not be too complicated, therefore, the design of the cylindrical hole grinder and general cylindrical hole grinder design, has its own Features. This article discusses the design of a hole grinder with a diameter of φ1 ~ φ4. The requirements for this type of abrasive: ① Diameter smaller than the diameter of the workpiece 0.01 ~ 0.025mm; ② the length of the working part of the general length of about 1/2 of the workpiece. Abrasive design, should first press the aperture size, work
